This is actually a debate we have had in IT, many times, as we are implementing systems changes to ensure we comply with the Digital Accessibility requirements by the DOJ (https://www.ada.gov/resources/2024-03-08-web-rule/). Finding the 'right' balance between the extra work/burden and the rights of the disabled, is more difficult than it may seem, especially when there is limited time, money and other resources involved - so perhaps the use of the American Indigenous Ethics framework would balance better.

This actually feels like the opposite of Ethics. Is egoism really 'rational'? I think we could easily argue no - how many happy, healthy, loved people exist that live only for their own self interest?

The concept of considering the balance of all parts of the ecosystem in which we live is especially intriguing to me. I appreciate the idea that Ethics considerations go beyond just person to person. We only exist as a part of a larger system - with air, water, land, plants - all in need of balance. Maximizing for people, can easily mean the deterioration for one of the other resources - considering the balance from the beginning would be wise it seems.
